By removing the.

springsr43 and rotating thepipe' member through one hundred twenty degrees clockwise of Fig. I,the

Positionedin the bore of the: pipemember 34 is a discharge guiding. pin member :44 whichisvof a diameter substantially equal to the internal. diameter of the reducedportion 36 so that members 34. and 44 are'substantially relatively. rigid. The member 44 projects from thelower end of member 34 and is provided with-a substantially conical end 45- op'erableto engage 'in'the fill'et'vor throat between the face and flange 'ofa The member44 is adjustably locked or heldiin member 34 bymeans of a detentor pinmember 46.

The springs 43 are placed under sufficient compression by the screws 38 to .-maintain.- the point 45 in position, and the inlet passage 31 is connected, as at 55, to a source of lubricantunderpressm'e, which is only operative to supplylubri'cant' during running of the locomotive.
